Fair enough, I didn't dig too deep though here's what I have come up with - I'm sure there are many factors, but it is quite interesting here:

Historically, Democratic and Republican administrations have followed distinct fiscal and economic patterns: Democrats typically oversee deficit reduction and falling unemployment, often achieved by maintaining or increasing the tax burden. Conversely, Republicans typically oversee deficit growth and rising unemployment, largely driven by decreased tax burdens through legislative cuts. Statistically, since 1945, real GDP has grown faster under Democrats (4.3% vs. 2.5%), while modern Democratic presidents (Clinton, Obama, Biden) have all reduced the deficits they inherited, whereas every modern Republican (Reagan through Trump) left office with a larger deficit than when they started

So you'd think tax cuts would create more jobs, less unemployment but it has not. It seems like the opposite, I'm sure there is much more to it.
